Steering and Suspensions
NOTE: By design, the BIASED COUPLE design of
the M-10 suspension displaces the rear arm as the
front arm is compressed. This means that when you
raise the front limiter strap, at some point you will
collapse the rear suspension arm, which will affect
SAG height and reduce rear suspension travel.
RAIL SLIDERS
Wear Limit
Replace sliders when wear exceeds notch. If sliders look
“wavy” in appearance, check and adjust track tension or
consider adding more bogie wheels.
Removal
1. Remove the rear suspension.
NOTE: Some models may allow the rail sliders to be
removed by sliding it through track windows with
the suspension mounted in the machine.
2. Remove front rail slider retaining bolt, located at the rail tip.
3. Use a block of wood or a drift punch and hammer to drive
the slider rearward off the slide rail.
4. With the rail slider at room temperature, install a new rail
slider by reversing steps 1 - 3.
NOTE: Lightly coat rail slider track clip area with a
lubricant such as LPS2 or WD-40 to ease installation.
Break-In
After installing new rail sliders they must be “broke in” for
longer life and better wear patterns. When performing the
breaking in procedure ride the sled on a surface that has
adequate snow conditions with deeper snow nearby. Run the
sled on the adequate snow surface and dip into the deeper snow
every so often.
REAR SUSPENSION REMOVAL AND
INSTALLATION
Removal
1. Support the rear of the machine so that the track is off the
floor.
2. Loosen the rear idler bolts, then push the rear idler shaft
toward the front of the machine.
3. Carefully release the torsion spring pressure (if equipped).
4. Remove the support from the tunnel letting the suspension
carry the weight of the machine.
5. Remove the fasteners securing the skid to the tunnel.
6. Place a protective mat on the floor and tip the unit over on
the left side, supporting the sled on the end of the handlebar.
7. Collapse the torque arms, and remove the suspension from
the tunnel.
Installation
1. With the unit on its left side, place the suspension in the
tunnel.
2. Align the front and rear torque arms with the tunnel
mounting holes. Loosely install two new fasteners.
NOTE: On IQ 121 and Switchback skids, verify the
rear track shock pivot and brackets are rotated
forward before attempting to collapse the rear
torque arm.
3. Set the machine upright.
4. Install the remaining two new torque arm mounting
fasteners.
5. Torque the rear suspension mounting bolts to specification.
6. Align the track guides/clips with the suspension rails.
7. Adjust the rear idler to achieve the correct amount of track
sag.

CAUTION
Always use new fasteners when securing the torque
arms to the tunnel.
